Origanum dictamnus 'Dittany of Crete'

 Origanum dictmamnus 'Dittany of Crete'
As the 'Holy Grail' for herb enthusiasts and something of a 'literary celebrity' in its own right, I was pleased to finally get my hands on this plant recently, though who exactly imported it, or the seed, would be interesting to know, as often such information in the Australian horticultural trade can be a closely guarded secret. While recorded as growing in European gardens as early as 1548 by herbalist William Turner, who wrote in his The Names of Herbs that he had seen it growing in Venice and Antwerp, he did not record its presence in English gardens until his 1568 Herball in which he wrote: " I have seen Dittany growing in England in Maister Riches garden naturally, but it groweth nowhere else that I know saving only Candy" ( the old name for Crete) The Hortus Kewensis confirms Turner and lists Dittany of Crete as "cultivated in 1551 by Mr John Rich". 
Fast forward to the early 20th century, in the US, the records of The Herb Society of America pinpoint its arrival there to the year 1936, brought over from Crete by one of its members, Mrs Ellery Sedgwick. who had procured a plant there from a woman who had been her cook in New York. Up until then herb growers had only been able to see what this ancient herb looked like from the specimen in the Gray Herbarium of Harvard University which had been collected in 1846 by Theodor Von Heldreich, Director of the Athens Botanic Garden. As Mrs Sedgwick recalled "The herb was some five inches high and had five or six little labiate flowers with protruding stamens at the ends of its branches, and resembled exactly the pictures of the specimens of Dittany at the Gray Herbarium of Harvard. Interest in the plant had also been sparked by the publication of the findings by British archaeologist Sir Arthur Evans (1851-1941) in his four volume Palace of Minos at Knossos (Macmillan Co. Publishers) where it was depicted on a fresco of birds perched amongst Cretan plants, this Caravanserai gave a window into the civilization of 1500 B.C..Sir Arthur was obviously a sharp eyed plantsman for he had already seen the wild plant growing in the crevices of rocks and described it as having 'rounded leaves like Pennyroyal ...lilac veined and covered with soft downy hairs, with a flower of a delicate purple hue emerging from a cluster of overlapping bracts 'and 'answering Virgil's description' In Virgil's Aeneid (29BC-19BC) Bk X11 tells of Venus helping to heal the wound of Aeneas.
"A branch of healing Dittany she brought
Which in the Cretan fields with care she sought.
Rough in the stem, which woolly leaves surround.
The leaves with flowers, the flowers with purple crowned.
Well known to goats; a sure relief
To draw the pointed steel and ease the grief."
The poem references goats which had long been observed nibbling on 'this sacred herb of Crete'  when wounded as an aid in their recovery.
So getting down to the nitty gritty of growing it in a climate which is just not like Greece in any way shape or form is a challenge. I am growing it in a pot in a mix of sand and perlite, not watering it much and keeping my fingers crossed that it survives the coastal humidity this summer. Taking cuttings to ensure a backup supply is advised for those like me who struggle to grow plants out of their comfort zone.
2017 update: Sadly lost my plant of it.

Hibiscus rosa-sinensis 'Captain Charles Louis Hope'

 Hibiscus rosa-sinensis 'Captain Charles Louis Hope'
This Hibiscus is shaded an interesting colour. Though technically described as 'light lime' it is closer, in certain lights, to a custard yellow or to a 'key lime pie'. The suffused deep rose centre is appealing and much like a beetroot stain on a t shirt might appear at this time of year.
It is a Queenslander and was bred by Alex Scott from a pod parent of 'Surfrider' and a pollen parent of 'Red Stripe', growing into a large bushy shrub with good glossy foliage.
I am intrigued why the name 'Charles' was included in the fore-name as it is not mentioned in the Australian Dictionary of Biography for the 'Honorable' Captain Louis Hope (1817-1894), the so called 'Father of the Australian sugar industry'. This is assuming that this Hibiscus was named in his honour.
 In 1864 Hope erected Queensland's first sugar mill at his property Ormiston on the banks of Hilliard's creek in Cleveland, Morteon Bay, using exploited/indentured labour ie. black slaves from the South Sea Islands while completely displacing the traditional landowners, the Koobenpul people, who left behind as evidence of their culture 'Bora rings' and 'canoe trees'. To his credit, Hope was an enthusiastic horticulturalist, importing thousands of plants for his extravagant garden at Ormiston, which included a scarlet Hibiscus arch of interwoven branches under which carriages were able to shelter. Little remained of the garden by the middle of the 20th century, over-taken in the sub-tropical heat by rampant Lantana and Bougainvillea. It was given a makeover in the early 1980's with a planting of Camellias and Agapanthus.  The garden includes a memorial Cairn to Hope which was erected in 1935. Ormiston House is a fine example of colonial architecture and is open to the public for numerous  events throughout the year.

Sansevieria in flower



Sansevieria ssp. flowering stem
Sansevieria or 'Mother-in-laws-Tongue' can be tricky to grow outdoors in climates outside the tropics. I have given up trying to grow some species as each year during winter they develop brown spots on the leaves which often turn mushy and rot out or the top leaves burn off and die downwards. They are a tough plant however and new shoots appear in summer from the massive rhizomatious root system which has the power to break through plastic pots in search of new ground to conquer. Flowering stems appear from time to time over summer and these always draw the eye as they seem like an explosion of greenish yellow petals. The red or orange fruits which follow ripen slowly and these contain seed which are fairly easy to germinate though new plants are slow to reach a good size. Propagation is more easily carried out by division of mature plants. In the meantime my collection of Sansevieria plants languish at the back of the Nursery and only occasionally get a once over tidy up such is their ability to survive with just the water that falls as rain.

Nigella damascena

Nigella damascena (Ranunculaceae)
 Earlier this month I tried to grow a batch of Nigella in 140mm pots as a commercial plant for sale in the nursery trade markets. This proved difficult as it is a plant which resents being transplanted once the seeds have germinated. Losses were high so I abandoned the project and it proved that it really prefers to hangout in a semi shaded garden corner in moderately rich garden soil where it can do its thing without disturbance, usually self seeding and returning each year if it happens to like the location. A cooler more temperate climate than mine may have helped in successful growing of it also.
The 'Persian Jewels' mix of Nigella contains some wonderful colours including a true sky blue , a deep purple, a crushed strawberry pink and of course white as shown here. The bonus with growing it is for the seed pods or capsules which are also decorative and these can be picked and used in dried flower arrangements.
Common names abound for this plant and include the English, Love-in-a-Mist or Devil-in a-Bush, the latter name referencing those horny little protuberances which top the flower. Other common names reference the veil of delicate, spidery or lacy foliage bracts which surround the flowers. It is a true texture or 'stroke me' plant ideal for sensory gardens. The German Venushaarige braut im haaren (Venus haired bride) or Jungfer im grunen (bridesmaid in green flower) paint the picture nicely of this fennel like foliage.
The other species of Nigella which I have yet to grow, N. sativa, yields the seed which is sometimes goes by the name of black cumin.The aromatic and pungent seeds are more commonly used in Middle Eastern and Indian cuisine. The Indian panch phora is a mixture of nigella seed, cumin seed, fennel, fenugreek and mustard seed.There is also a tradition of using the seed as a topping for bread especially in eastern Europe where the heavy rye style loaves, which weigh a ton and just one slice will fortify you for a hike through a blizzard, are popular. I am thinking here of the Russian chernuska rye bread or the German black bread with schwartzkummel. 
Nigella spice seed remains less well known in Australia but the flowering species has been a popular cottage garden flower for many years.

Hibiscus rosa-sinensis 'Swan Lake'

 Hibiscus rosa-sinensis 'Swan Lake' syn. 'Dainty White' syn. 'White La France'
This is another familiar old garden Hibiscus which has been grown for decades since its introduction from Florida. The pure white flower, which is occasionally flushed with green or cream on the petal edges, is a miniature windmill type of about 125mm and it originally appeared as a sport on 'Dainty Pink'. Pink flowers may still sometimes occur depending on the time of year. This is a very tall growing bush with whip-lash stems covered in only tiny leaves. If left un-pruned it develops a slightly weeping habit with age. The fashion for trimmed and pruned-within-an-inch-of-their-life shrubs has left this Hibiscus out in the cold somewhat but it is certainly worth including in a wild tropical style garden where a splash of white tempers more hot vibrant colours of foliage and flowers.

Hibiscus rosa-sinensis 'Enid Lewis'

Hibiscus rosa-sinensis 'Enid Lewis'
 Enid is an old fashioned name as is this variety of Hibiscus. It was originally grown by the great Australian Hibiscus nurseryman from the Sydney suburb of Warringah, Les Beers, who established Hibiscus Park Nursery there in the late 1950's. The suburb is now famous for its Mall.......This small flowered Flamingo pink variety is flushed with a biscuit colour at the edge of the petals and on the reverse. It is not a huge flower only being about 125-150 mm wide but is a '2 dayer'. It flowers for most of the year and over winter the flowers shrink and become quite miniature and look quite sweet. Les Beers selected this variety when it appeared as a sport on 'Sabrina' which in turn had originated from the aforementioned 'Mrs George Davis' or Kona. It is a tall growing variety which becomes gnarly with age but can be kept pruned to a more manageable height. It is a recommended variety for growing in a partly shaded location.

Hibiscus rosa-sinensis 'Mrs George Davis'

 Hibiscus rosa-sinensis 'Mrs George Davis' syn 'Kona'
The rich rose pink double flowers of 'Mrs George Davis' are a familiar sight in many old gardens up and down the coast. This vigorous tall growing variety, which originated in Hawaii in the 1950's, is a popular choice for use as a hedge or screen and in warm climate gardens it will flower for most of the year. It has few of the pest or disease problems which can affect some of the more flamboyant modern hybrids, suffering no die-back or borer as it matures. Regular pruning each year and a dose of Hibiscus fertilizer ensures a healthy flush of new growth and continuous flowering. This variety has given rise to a couple of good 'sports' or flowers which have appeared on the bush as a different colour from the original. These are the Cardinal red 'Sabrina' and the peaches and cream 'Mrs Andreasen', both doubles and very hardy varieties.
